Thanks, Ilya, I just ran into this problem when trying to OVN :)

commit 361a47d66 ("flow: Fix using pointer to member of packed struct 
icmp6_hdr.")
in OVS updated 'struct icmp6_error_header' with renaming it to
'struct icmp6_data_header'.

OVN should update names of a structure and constants accordingly.

This is a copy-paste from the OVS 2.12 branch.
I didn't try to compile this with code from OVN repo.
